Budget carrier Ryanair is expecting to have only 10 Boeing 737 Max jets available for its summer 2020 season, a further cut in its capacity forecast for the season.
The airline had originally planned to operate 58 of the re-engined type next summer.
But it halved this to 30 after the grounding of the 737 Max in March, and subsequently cut its outlook again, to just 20 aircraft, in November.
Ryanair has again pulled back the capacity forecast, expecting just 10 Max jets to be available for the summer season.
It says it has revised its schedule to account for the absence of the aircraft, and says the delays to delivery will "necessitate" the closure of it bases in Nuremberg and Stockholm Skavsta in 2020.
The airline had positioned two and four aircraft at these bases respectively. Ryanair insists that the closures are "solely" due to the Max hold-up.
"We also expect to cut summer capacity in a number of other existing bases, and we are currently in discussions with our people, our unions, and our affected airports to finalise these minor reductions," says the carrier.
Ryanair is trimming its passenger number outlook to 156 million for the year to 31 March 2021.
